摘要

利用钼酸钠前驱体,通过水热法合成了钴促进的 MoS2 微球。扫描电子显微镜显示出球形形态,铯校正透射电子显微镜显示在对应于(101)面的 MoS2 边缘检测到钴原子。通过磁化曲线测量磁态,得出顺磁贡献为 0.044 emu/g。此外,从 2H-MoS2 的状态密度(在 (101) 边缘平面有钴和没有钴)得出的电子结构具有磁性,其值为 0.16 μB,这归因于对称性被打破。

The magnetic states in cobalt-promoted MoS2 microspheres

The magnetic states in cobalt-promoted MoS2 microspheres

The cobalt-promoted MoS2 microspheres have been synthesized by hydrothermal methods using sodium molybdate precursors. Scanning electron microscopy indicates that spherical shape morphology and cobalt atoms are detected at MoS2 edges corresponding to (101)-plane as revealed by Cs-corrected transmission electron microscopy. The magnetic states were measured by magnetization curves obtaining a 0.044 emu/g due to paramagnetic contribution. Furthermore, the electronic structure from the density of states for 2H-MoS2 with and without cobalt at the (101) edge plane possesses a magnetic property with a value of 0.16 μB attributed to broken symmetry.
